Synopsis

Description

This routine outputs either the integer value 2 (if (out.flags() & std::ios_base::boolalpha) == 0) or the name of the indeterminate value. The name of the indeterminate value comes from the indeterminate_name facet (if it is defined in the output stream's locale), or from the get_default_indeterminate_name function (if it is not defined in the locale or if the C++ standard library implementation does not support locales).
